Botanic information
Leaf: The leaves are reduced to 9 to 16 triangular scales that are arranged in whorls around the nodes along the cladode. The dark green branchlets become blue-grey in the cooler months.

Flower: The brown male flowers appear in a short spike towards the end of the branches and the female flowers may appear on a different tree during early spring.

Fruit: The woody ovoid (barrel shaped) and cone-like fruit is up to 12 mm (½ in) wide and contains numerous capsules. The angular valves are exserted giving it a rough texture.
